Rezumat
In lucrarea de fata se prezinta o metoda de optimizare, din punct de vedere electromagnetic, a constructiei unei masini sincrone cu magneti permanenti plasati direct in intrefier, fara perii. Scopul acestui studiu este, pornind de la o valoare impusa a cuplului de sarcina, identificarea valorii optime a razei exterioare de curbura a magnetilor permanenti,
plasati pe rotorul masinii electrice studiate, astfel incat atingerea valorii dorite a cuplului sa se realizeze in conditiile utilizarii unui volum minim de material magnetic si la un curent statoric minim.

Abstract
The paper presents the rotor design of a brushless synchronous bread-loaf permanent magnet machine (PMSM), while the following restrictions are present: requested load torque, minimum current, minimum permanent magnet volume. The optimized parameter under study is the top curvature of the permanent magnets. The optimization is performed while monitoring related electromagnetic indicator quantities, such as the air-gap magnetic flux waveform,
saturation and the amount of magnet material.
